Photon-phonon entanglement in coupled optomechanical arrays

By Uzma Akram, William Munro, Kae Nemoto and G. J. Milburn

Abstract

We consider an array of three optomechanical cavities coupled either reversibly or irreversibly to each other and calculate the amount of entanglement between the different optical and mechanical modes.We show that the composite system exhibits intercavity photon-phonon entanglement
